Abstract
Abstract A sonic detector for sensing substantially horizontally moving sonic waves comprising a sectional housing having a transducer means carried therein. One section of the housing is provided with an outwardly extending radial flange for intercepting the horizontal sonic waves and transmitting sliding movement to the section with respect to the other housing section. The sliding movement of the said housing section provides activation of the transducer means for producing a signal. This invention relates to improvements in detection methods and means and, more particularly, but not by way of limitation, to a system and means for detecting unwanted personnel or intruders encroaching upon an area surrounding and at a distance from a given site.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
62 words
A sonic detector comprising a first housing, a second housing slidably secured to the first housing, transducer means carried by the two housings, means provided on the second housing for intercepting substantially horizontally moving sonic waves for transmitting sliding movement to the second housing, said sliding movement of the said second housing providing activation of the transducer means for producing a signal.
Claim 2
Dependent Claim
62 words
A sonic detector comprising a first housing, a second housing slidably secured to the first housing, transducer means carried by the two housings, means provided on the second housing for intercepting substantially horizontally moving sonic waves for transmitting sliding movement to the second housing, said sliding movement of the said second housing providing activation of the transducer means for producing a signal.
Claim 3
Dependent Claim
105 words
A sonic detector comprising a first housing, a second housing slidably secured to the first housing, means cooperating between the two housings for facilitating relative movement therebetween, coil means carried by the first housing, magnet means carried by the second housing and cooperating will the coil means to provide a transducer, means provided on the second housing for intercepting substantially horizontally moving sonic waves for transmitting sliding movement to the second housing with respect to the first housing, and said relative movement between the two housings providing relative movement between the magnet means and the coil means whereby a signal is produced by the transducer.
Claim 4
Dependent Claim
105 words
A sonic detector comprising a first housing, a second housing slidably secured to the first housing, means cooperating between the two housings for facilitating relative movement therebetween, coil means carried by the first housing, magnet means carried by the second housing and cooperating will the coil means to provide a transducer, means provided on the second housing for intercepting substantially horizontally moving sonic waves for transmitting sliding movement to the second housing with respect to the first housing, and said relative movement between the two housings providing relative movement between the magnet means and the coil means whereby a signal is produced by the transducer.
Claim 5
Dependent Claim
122 words
A sonic detector comprising a first housing, a second housing slidably secured to the first housing, lubricating means cooperating between the two housings for facilitating relative movement therebetween, coil means carried by the first housing and disposed internally thereof, magnet means carried by the second housing and disposed internally thereof for cooperating with the coil means to providE a transducer, a radially outwardly extending flange provided on the outer periphery of the second housing for intercepting substantially horizontally moving sonic waves for transmitting sliding movement to the second housing with respect to the first housing, and said relative movement between the two housings providing relative movement between the magnet means and the coil means whereby a signal is produced by the transducer.
Claim 6
Dependent Claim
122 words
A sonic detector comprising a first housing, a second housing slidably secured to the first housing, lubricating means cooperating between the two housings for facilitating relative movement therebetween, coil means carried by the first housing and disposed internally thereof, magnet means carried by the second housing and disposed internally thereof for cooperating with the coil means to providE a transducer, a radially outwardly extending flange provided on the outer periphery of the second housing for intercepting substantially horizontally moving sonic waves for transmitting sliding movement to the second housing with respect to the first housing, and said relative movement between the two housings providing relative movement between the magnet means and the coil means whereby a signal is produced by the transducer.
Claim 7
Dependent Claim
108 words
A sonic detector comprising a first housing, a second housing slidably secured to the first housing, means cooperating between the two housing for facilitating relative movement therebetween, coil means carried by one of said housings, magnet means carried by the other of said housings and cooperating with the coil means to provide a transducer, means provided on the second housing for intercepting substantially horizontally moving sonic waves for transmitting sliding movement to the second housing with respect to the first housing, and said relative movement between the two housings providing relative movement between the magnet means and the coil means whereby a signal is produced by the transducer.
Claim 8
Dependent Claim
108 words
A sonic detector comprising a first housing, a second housing slidably secured to the first housing, means cooperating between the two housing for facilitating relative movement therebetween, coil means carried by one of said housings, magnet means carried by the other of said housings and cooperating with the coil means to provide a transducer, means provided on the second housing for intercepting substantially horizontally moving sonic waves for transmitting sliding movement to the second housing with respect to the first housing, and said relative movement between the two housings providing relative movement between the magnet means and the coil means whereby a signal is produced by the transducer.
